plugging in huey colorimeter locks user in login screen

[Alexander Graf]

Plugging in a huey colorimeter (for screen color calibration) after booting to the login screen opens a window which gains focus and the user is unable to log in.

Steps to reproduce:

* Boot to the login screen.
* Do NOT login.
* Plug in a huey colorimeter (lsusb says "ID 0971:2005 Gretag-Macbeth AG Huey") into a USB port (maybe another colorimeter triggers the same behaviour).
* The System Settings->Color dialog opens and you can not proceed to login nor you can close the window since it has no default window buttons (close etc.).
